Accolades
Manny was the only Wright homeowner present at the inception of the Frank Lloyd Wright Building Conservancy.

Manny was also the first Wright homeowner to donate an easement on a Wright house to the FLWBC as well as donating one original spare Tomek House window to the Art Institute of Chicago and one to the Frank Lloyd Wright Home & Studio Foundation.

The Tomek House and Garden were visited by many, sometimes two thousand people per year. Prof. Charles Aquar, compiling case studies for his book on Wright’s landscaping wrote about the Tomek Garden: “The well-thought-out and executed plan proves that the typical registered landscape architect could not necessarily match the skills of an artist whose avocation is gardening and who is aware of the changing light, viewing angles, seasonal cycles, and sensory experiences that can only come by living in and experiencing a Wright-design residence.”

From the Graham Foundation on Down To Earth:
“Her scholarship has established the seminal importance of the Tomek House in American architectural history. It was the first to exploit the long cantilever, mother of the Robie House and grandmother of Falling Water.“

Prof. Paul Sprague, reviewing Down to Earth for the Journal of the SAH wrote: “She designed, planted and maintained informally arranged gardens which could not have been better planned by architect Walter Burley Griffin.”
